6. Maintaining the Machine
Replacing the Print Cartridge
• Store print cartridge in a cool dark place.
• Actual printable numbers vary depending on image volume and density, number of pages printed
at a time, paper type and size, and environmental conditions such as temperature and humidity.
Toner quality degrades over time. Early replacement of the print cartridge might be necessary.
Therefore, we recommend you always keep a new print cartridge ready.
• For good print quality, the manufacturer recommends that you use genuine toner from the
manufacturer.
• The manufacturer shall not be responsible for any damage or expense that might result from the use
of parts other than genuine parts from the manufacturer with your office products.
• When the toner runs out, pressing the [Stop/Start] key allows you to print a few more pages, but
the print quality of those pages may be lower.
